The problem is that the correct answer is

\(\displaystyle -1 \pm \dfrac{\sqrt{30}}{5}\)

not

\(\displaystyle \dfrac{-1 \pm \sqrt{30}}{5}\)

you actually got the second one correct, and probably typoed the first one somewhere.

Oh, I see. I concatenated the –1 into the first answer, and then failed to see that I could factor it out of the second. Thank you!
